Hi just had a look at the spring leaded bobbin remover video, so clever, I think even I can do it with your method. Never really thought that was such a good idea of Elna, but not one of mine ever broke. These Elnas were indistinguishable. Only a small amount of oil and working for many hours a day. I also didn't have money for services, just kept them clean and on we went. Thanks Anita
